TUG-STRAP HOLDER FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 405,418, dated June 18, 1889. Application filed September 2'7, 1888. Serial No. 286,528. (No model.) Patented in England August 20, 1888, No. 11,990;

ing drawings, forms a full, clear, and exact description. I

This invention relates to improvements on I tug-strap holders for looms, and particularly to an improvement on a sliding tug-strap holder for power-looms for which a United States Patent No. 351,7 7 9 was granted to me on the 2d day of November, A. D. 1886; and

this invention consists of devices for rigidly and firmly securing the tug-strap holder at the position to which it is adjusted onthe picking-stick to completely prevent any possibility of the sliding tug-strap holder or its securing devices from becoming accidentally displaced under any circumstances whatever, as will be hereinafter more fully described and claimed.

Reference is had to the accompanying d rawings already mentioned, wherein- 0 Figure 1 is a side elevation of a tugstrap holder, as well as of its securing devices, as applied to a pickin stick. Fig. 2 is an edge View of the same, showing the securing devices disengaged from each other. Fig. 3 is 3 5 a side elevation of a modification of the tugstrap holder and plate-fastener shown in Fig.

1. Fig. l is an edge view of same, showing the tug-strap holder partly in section and the plate-fastener disengaged therefrom.

In operating the invention illustrated in my United States patent, hereinbefore mentioned, I find that the jar of the picking-stick D is liable to displace the nut E, mentioned therein, and thereby loosen the sliding tugstrap holder A. If the nut E were accident ally displaced by the jar of the pickingstick, the tug-strap holder A would also become loose on the picking-stick. The operator would then have to pass around and be continually tightening the nut E which or its substantial equivalent E, rigidly secured to which or formed integrally therewith 1 is a ratchet R, for the purpose of rigidly holding the ratchet R in place and to prevent it from turning when it is bound aganstthe plate-fastener G. p G designates a plate-fastener, interposed between the ratchet R and tug-strap holder 7a A. This plate-fastener G is provided with projections P, which loosely engage with corresponding recesses H in the tug-strap holder A, as shown in Figs. 3 and 4. These projections P may engage with recesses H between cogs J on the holder A, as in Figs. 1 and 2, or the projections P may be formed on the tugstrap holder A and the recesses H formed in or on the platefastener G, as found most suitable or convenient under the circum- 8o stances, so that when the thumb-nut E is tightened these projections P engage with the recesses II and firmly hold the plate-fast: ener G in place on the tugstrap holder A, and at the same time prevent either from moving independently of the other.

K designates a pin or bolt, rigidly secured to or formed integral with the plate-fastener G, and L is a dog pivoted on this pin or bolt K, and between this dog L and a shoulder or overhanging head K of this pin or bolt K a coil-spring N is interposed, as shown in Fig. 2 of the accompanying drawings, and this pin or bolt K is secured in proper position on the plate-fastener G, so that the outer end of the dog L will engage with the ratchet R. This coil-spring N is for the purpose of preventing the accidentaldisplacement of the dog L from the plate-fastener G; and S is a flange or stud formed on the plate-fastener G to pre- I00- j the required pick.

vent the dog L from being accidentally moved laterally from engagement with the ratchet R. The jar of the picking-stick D when in operation is liable to displace this dog L if not firmly held and secured in place by the spring N and studor flange S. At the same time, when it is required to adjust the sliding tug-strap holder. A up or down on the pickingstaff D, to cause the latter to give a more or less forcible pick, the spring N permits the dog L to be grasped by the hand and moved from the plate-fastener G, thus compressing the spring N until the dog L clears the stud or flange S, when the dog L may be moved out of the way of the ratchet R to the position shown in Fig. 2. This permits the loosening of the thumb-nut E and ratchet R from the plate-fastener G, and permits of the adjustlnient of the tug-strap holder to the proper position, so that the picking-stick will give I When properly adjusted, t is held in that position by adjusting the plate-fastener so that the projections P will come opposite the recesses H, and by turning the thumb-nut E until the lower side of the "ratchet R binds the fastener and tug-strap until it clears the stud or flange S and engages with the ratchet R between the latter and the ilange or stud S and spring N. x This invention has been described as securing a tug-strap holder to a picking-stick, but it would work equally well in securing 3 5 and locking other objects together.

Having thus described my invention, I claim 1. A plate-fastener G and a tug-strap holder A, one having recesses H and the other projections P, fitted loosely to said recesses, in combination with means for clamping them together and to the side of a picking-stick, as and for the purpose set forth.

2. The stud or flange S, in combination with the plate-fastener G, pin or bolt K, having head or shoulder K, spring N, dog L, thumbnut E, ratchet R, and bolt E, as and for the purpose set forth.

3. A plate-fastener Gand a tug-strap holder A, one having recesses H and the other projections P, fitted loosely to said recesses, in combination with a picking-stick and means for clamping them together and to the side of the picking-stick, as and for the purpose set forth.

4. A plate-fastener G and a tug-strap holder A, one having recesses H and the other projections P, fitted loosely to said recesses, in combination with a ratchet R, thumb-nut E, bolt E, picking-stick D, dog L, spring N, pin K, formed with shoulder K, and stud or flange S, as and for thepurpose set forth.

In testimony whereof I affix my signature in the presence of the two undersigned witnesses THOMAS KENDRAY.
